苹果第二次拒绝了我的应用

Question

我创建了一个应用程序，但苹果两次拒绝接受不遵循ios数据存储准则的信息，我感到惊讶，因为我已经提交了应用程序而没有任何问题，我正在使用sqlite来存储我的数据，并且正在将图像存储到文档目录及其路径中进入数据库，我已经做了

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    const char* filePath = [[URL path] fileSystemRepresentation];

    const char* attrName = "com.apple.MobileBackup";
    u_int8_t attrValue = 1;

    int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
    return result == 0;
}

-(void) copyDatabaseIfNeeded {

    //Using NSFileManager we can perform many file system operations.
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error;
    NSString *dbPath = [self getDBPath];
    BOOL success = [fileManager fileExistsAtPath:dbPath];

    if(!success) {
        NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:databaseName];
        success = [fileManager copyItemAtPath:defaultDBPath toPath:dbPath error:&error];

        [self addSkipBackupAttributeToItemAtURL:[NSURL URLWithString:dbPath]];

        if (!success)
            NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);
    }
}

-(void)connectWithDB
{
    [self copyDatabaseIfNeeded];
    [self generateDB];
}

在我的booldidfinishWithLaunchingOption函数中

[self connectWithDB];

我不知道为什么会有问题

We found that your app does not follow the iOS Data Storage Guidelines, which is required per the App Store Review Guidelines.

In particular, we found that on launch and/or content download, your app stores 2.5 MB. To check how much data your app is storing:

Install and launch your app
Go to Settings > iCloud > Storage & Backup > Manage Storage
If necessary, tap "Show all apps"
Check your app's storage

您使用的是旧方法。 使用本文档中描述的更新方法

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);

    NSError *error = nil;
    BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
                              forKey: NSURLIsExcludedFromBackupKey error: &error];
    if(!success){
        NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
    }
    return success;
}
